Unable to select hard drives

[jreffner]

I also have had the same problem lately. I've been used SD! for years and have never seen this. I too, am running Snow Leopard. If you do a Get Info on the external HD that SD has grayed out, you'll notice that part of the permissions claim that the disk is "Read Only". Unlocking this and then changing it to "Read & Write" fixes the problem, but you'll be back to the same problem after rebooting. Repairing permissions with Disk Utility, Cocktail, or Drive Genius doesn't fix it either. Sometimes you can't even manually change the permissions in the "Get Info" box without restarting first. Something is changing the permissions on these disks and I don't know what it is, but I suspect that it may have something to do with the newly released Bootcamp drivers (3.0 I think) that allow Windows 7 to read and write HFS+ disks. I have no evidence of this, but it seems that this happened to me after I installed the Bootcamp drivers.

Any thoughts?
